          Parameters
          ----------
          initial_condition : <string> or <tuple>
              Takes on one of the following sets of values:
  
              * 'original'/'o' : Reset to the model-file specified initial condition.
              * 'current'/'c' : Use the current state of the system to start
                the next simulation. This includes the simulation time, so this
                initial condition must be paired with new return timestamps
              * (t, {state}) : Lets the user specify a starting time and list of stock values.
  
          >>> model.set_initial_condition('original')
          >>> model.set_initial_condition('current')
          >>> model.set_initial_condition((10, {'teacup_temperature': 50}))
